The Battle of Bosworth (& lead-up)

Henry's invasion & march to Bosworth

Richard knew Tudor was seeking refuge in Brittany so struck a deal with Duke Francis II; Richard would supply English archers to defend Brittany from French attack if they no longer allowed Tudor's safety. Therefore Tudor's were forced to flee, heading to FRANCE.

This move actually ENCOURAGED further actions against Richard...

Enraged by Richard's hostile actions, King Charles VIII of France welcomed Tudor and granted them with financial & military support against Richard (it was mutually beneficial, because Tudor was attacking England, Charles could focus efforts on taking Brittany for France without English intereference)
